り拭き取り作業中の溶出が問題となる。[0003] A wiper made of a sheet composed of 100% pulp is required to have a certain degree of flexibility from the viewpoint of use in a wiper. Therefore, with a single sheet, there is an upper limit on the basis weight, and it is difficult to secure a high water absorption. (Up to about 50 g / m 2 ) In order to solve this problem, a plurality of sheets are laminated. As a laminating method, mechanical means by adhesive bonding and pin embossing are usually performed, but in the former, the elution of the adhesive during the wiping operation becomes a problem, and in the latter, a hole is opened in the sheet. There is a problem that the strength when wet is greatly reduced. Further, there have been proposed a sheet made by a double reclaim machine, and a wiper having a high and high water absorption by an air-laid pulp nonwoven fabric. However, these contain a large amount of binder, which causes a problem of elution during the wiping operation.

にコスト高となるのが通常である。A wiper in which a pulp is combined with a nonwoven fabric has also been proposed. A wiper in which a spunbond nonwoven fabric and pulp fibers are hydroentangled has been proposed. However, in this method, a high degree of entanglement treatment is performed under a high water pressure for the purpose of preventing the pulp fiber from falling off, so that the bulk is reduced and it is hard to say that the method has a sufficient absorption capacity. Also, such a hydroentanglement process is usually very costly.
